请求未找到ajax spring mvc

我有一张桌子。当我单击删除图标时,我想从数据库中删除该人,并成功从表中删除该行。我不断deleteEmployee?id=37 not found

404。我有一个控制器@RequestMapping(value = "/deleteEmployee", method =

RequestMethod.GET)。我单击的人已从数据库中删除(选中),因此控制器应该没问题。但是为什么会出现错误?

@RequestMapping(value = "/deleteEmployee", method = RequestMethod.GET)

public void deleteEmployee(@RequestParam(value = "id", required = true) int id) {

System.out.println(id);

employeeDAO.deleteEmployee(id);

}

$(document).on('click','.delete-emp', function(){

deleteEmployee(this);

});

function deleteEmployee(el){

var id = $(el).parent().attr('data');

console.log("delete: "+id);

$.ajax({

url: "deleteEmployee?id="+id,

success: function(){

deleteRow(id);

}

});

}

function deleteRow(el){

var row = $('.employee-row[data='+el+']');

var shiftRow = row.next();

console.log("deleting "+row+" "+shiftRow);

row.remove();

shiftRow.remove();

}

回答:

仅在方法中使用@ResponseBody注释就足够了。这将解决您的问题。

@RequestMapping(value = "/android/api/home", method = RequestMethod.GET, produces=MediaType.APPLICATION_JSON_VALUE)

public @ResponseBody void Home(Locale locale, Model model,HttpServletRequest request,HttpServletResponse response) throws IOException {

//your logic

}

在ajax调用中添加内容类型

jQuery

.ajax({

url : controllerUrl,

data : oMyForm,

dataType : 'text',

processData : false,

contentType : false,

type : 'POST',

success : function(data) {

}

});
